智能卡操作终端面临的安全攻击及其防御

Attacks and Countermeasures on Smartcard Operating Terminals

智能卡操作终端的安全性在智能卡应用系统中处于重要地位。本文首先通过分析指出智能卡终端是系统中最易受攻击的部分,然后建立了一个四维空间用于分析描述终端面临的安全攻击,分别阐述了针对不同层次的攻击和威胁,并提出了防御措施。

The security of Smartcard operating terminals is very important in a Smartcard application system. First, analysis shows that a Smartcard operating terminal is the most vulnerable area in the whole system. Hence, a 4-D space is constructed to describe security attacks. Finally countermeasures are proposed, which is against the attacks from different levels.
